MG-A01 supports concurrent reception of GNSS (GPS, GLONASS, , and BeiDou). The high number of visible satellites enables the receiver to select the best signals. This maximizes the position availability, in particular under challenging conditions such as in deep urban canyons. Super-S (Super-Signal) technology offers great sensitivity and can improve the dynamic position accuracy in non-line-of-sight scenarios.
